Bad service with a lot of threats

I been a BFS customer for 2 years and never missed a payment, but this month I had issues with employer . I received a call from the manager (Tonga mall) where I explained that I still have issues to deal with and I will pay. The other day I received a call from a cellphone phone from Bfs consultant where he was so rude and threaten me that he will cum to my work place if I don't pay the funds. He even mentioned that he knows where I'm staying. 8 did try to explain to him that you don't treat a customer like that more especially using your cellphone number, why can't 7 ask me why I'm unable to pay the loan. And he responded and say his boss want the repayment. Due to his bad customer service I started complaining about his approach and he hang up the phone. One of my neighbors told me that a certain guy driving BFS car was looking for me and then immediately I called the branch and asked to speak with branch manager where even management was so rude. Cause I wanted to understand the reason for visiting my place and where did they got all the information about my residence. And also need a contract where it says they can to my place for loan repayment. Branch manager for Tonga branch was rude and she explained that the financial situation the guy have a right to do everything since I owe them and they want their money back. I did try to teach her about good customer service since I was once a branch manager but she promised that she hang the phone or she will leave the phone unattended. instead the staff member was rude called me a **** indirectly and basically belittled me then cut the call and said she will come see me at work. It's seems like they operate on loan shark mafia principles and not like normal financial institutions. There are many loan providers, I advise all to stay away from BFS.
